CAN YOU USE THE
QUICK START GUIDE?
Use this Quick Start Guide if...
1. Your system uses a Hazardous Area X-STREAM O
2
Transmitter without
the SPS 4001B or IMPS 4000 autocalibration options.
2. Your system does not use traditional architecture or remote electronics.
(Refer to Section 1: Description and Specifications for a description of
"traditional architecture").
3. You are familiar with the installation requirements for the Hazardous
Area X-STREAM O
2
Transmitter.
If you cannot use the Quick Start Guide, turn to Section 2: Installation, in
this Instruction Manual.
If this equipment is a direct replacement (DR) version of the Hazardous
Area X-STREAM O
2
Transmitter, refer to the manual for your Legacy
electronics.
OVERVIEW
The X-STREAM is Rosemount Analytical's latest in-situ probe offering
intended for combustion flue gas service. Similar to our previous World Class
and Oxymitter probes, there is no sampling system. The sensing cell is
mounted to the end of a probe (18", 3', or 6’ long) that is directly inserted into
the flue gas stream.
The sensing cell is of similar design to the World Class and Oxymitter cells,
utilizing the zirconium oxide sensing principle. The cell is heated and
maintained at a 736°C (1357°F)
setpoint, and generates a logarithmic MV
signal proportional to the partial pressure difference of oxygen between the
reference side of the cell (usually instrument air at 20.95% O
2
), and the
process side of the cell (usually combustion flue gasses). For more
information on sensing cell operation, see the Overview of Operating
Principles in Section 5: Troubleshooting.
PROBE ARRANGEMENT
The probe consists of a "probe tube" and a "sensor core". The probe tube is
basically an empty stainless steel tube that mounts to the flue gas duct via a
2½" NPT male pipe thread, or a 2" 150# ANSI flange mount. Two housings
with covers contain the transmitter electronics and the sensing core. A conduit
port is provided for bringing in AC line voltage for the heater, and for the 4-20
mA O
2
sensing signal loop wires. Ports for cal gas and reference gas are also
provided.
